WebSep 28, 2024 · Step 1: Find Dunnett’s critical value. First, we must find Dunnett’s critical value. This is calculated as: Dunnett’s Critical value: td√2MSw/n. where: td: The value found in Dunnett’s Table for a given alpha level, number of groups, and group sample sizes. MSw: The Mean Squares of the “Within Group” in the ANOVA output table. WebThe table above provides the test statistic (χ 2) value ("Chi-square"), degrees of freedom ("df") and the significance level ("Asymp.Sig."), which is all we need to report the result of the Friedman test.From our example, …
